one of the fans in my pc didn't work, because the plug of the fan wasn't plugged in. when i pushed the plug back in and turned the computer on again, nothing was happening on the screen, and the keyboard didn't work either. though the monitor was on. it is possible i exidently touched something inside the pc while pushing the plug of the fan back in. could anyone help me with this problem?

Because i had to clean it, there was a lot of dust in the fan. When i turned it on after cleaning it, the computer worked fine, but the fan didn't. I saw it wasn't plugged in, pushed the plug of the fan back in. I Didn't turn it on immediatly, because i didn't need it. But when i did, like three hours later, i had this problemen. I just unplugged the fan, and it still didn't work.

still not working, i tried to reset the bios by using the jumper, and by reseating the cmos battery. I reseated the cpu too.
 
If you have the ability to replace the power supply with another, or test it, I would try that next. I'm hoping that a static discharge didn't happen when you were cleaning it and kill the mobo. The chances of the PSU failing right after cleaning it seem a little remote, though.
